this was originally for Pokeykat1 but is free for anyone to openly study <3
the back was too hollow
the hocks were set too high
the neck was displaying an unnatural hyperflexion
the face was too hollow
the muzzle was too round
the back needs to be for the most part straight - its a spine made of bone, the spine is only so flexible, for the flexion in the neck which you displayed it the back was far too hollow, a proper rounded frame has a set back and comfortably placed head which is set on a diagonal from the molars to the withers. the lower lip should not make contact with the breast, this is considered illegal hyperflexion behind the vertical and overall is poor conformation and unnatural. the highest point on the horses neck should be the poll , despite if the horse is framed, relaxed, or hollow. furthermore a horse's throatlatch is more defined. a horse's hooves are comprised of a barely rounded base, a steeper incline along the front, a diagonal across the cornet band, and a shorter incline along the back of the hoof.
hope this helps <3
